OpenAI is rolling out ‘Codex’ for ChatGPT, which is an AI agent that automates and delegates programming tasks for software engineers.
OpenAI isn’t explicitly claiming that Codex will eventually replace junior software engineers.
Instead, the company states Codex could help developers achieve more by delegating their tasks to different agents.
The idea is to move faster with development and become more productive with AI, but how does Codex work?
According to OpenAI, Codex is based on codex-1, which is a new version of ChatGPT based on the existing o3 model, but it has been optimized for coding, which results in increased accuracy.
Codex pulls codebase from Github and closely mirrors the existing PR style.
It can write new code, propose pull requests, and run each task in its own sandbox.
“Task completion typically takes between 1 and 30 minutes, depending on complexity, and you can monitor Codex’s progress in real time,” OpenAI noted in a blog post.
“Once Codex completes a task, it commits its changes in its environment. Codex provides verifiable evidence of its actions through citations of terminal logs and test outputs, allowing you to trace each step taken during task completion.”
Codex is rolling out, but only if you’ve a Pro subscription, which costs $200 per month.
